* Implement "TramplesMinimize" as a move flag
Implemented `TramplesMinimize` as a move flag. Due to it, removed effect codes `FlinchTargetTrampleMinimize` and `ParalyzeTargetTrampleMinimize` (the second one was exclusive to Body Slam). Moves that had them now have the effect codes `FlinchTarget` and `ParalyzeTarget`, respectively.
The code now does not check if the parameter of `tramplesMinimize?` is 1 or 2, it now checks if it is `true` or `false`. For the effect that causes the moves with this flag to skip accuracy checks, it also checks if `Settings::MECHANICS_GENERATION` is equal to or greater than 6.
Data on which moves are to be treated as able to double damage if Minimized and skip accuracy checks are [here](https://bulbapedia.bulbagarden.net/wiki/Minimize_(move)#Vulnerability_to_moves).
**Remarks:**
- Dragon Rush, Heat Crash and Heavy Slam could not trample Minimize in Gen 5. Dragon Rush and Heat Crash could do so in Gen 6+, but Heavy Slam could not until Gen 7.
- Double Iron Bash could only trample Minimize in Gen 7.
**TL;DR:**
- Implemented `TramplesMinimize` as a move flag.
- Modified the check for this move flag.
- Removed effect codes `FlinchTargetTrampleMinimize` and `ParalyzeTargetTrampleMinimize`. Moves that had them now have the effect codes `FlinchTarget` and `ParalyzeTarget`, respectively.
